| Abstract: |
In this paper, the two physical models for the porous solar wall heating system with localized underfloor air distribution (UFAD), and the one with ceiling air supply are established, respectively.Based on Brinkman-Forchheimer Extended Darcy and energy two-equation models for saturated porous medium, the heat transfer and flow characteristics of two kinds of system are simulated and analyzed by using numerical simulation. The results show that the localized underfloor air distribution (UFAD) has better performance on flow and temperature distribution, utilization of solar power than the localized ceiling air supply for the porous solar wall heating system. |
